i This invention relates to improvements in fly chasers and contemplates the provision of a roller which is arranged between the upright of a door frame and which further includes a plurality of strips depending from diametrically opposite sides thereof and which when rotated will chase or frighten flies or other insects from the doorway when the door is open. 7 Another object of the invention is'the provision of spring means included within the roller which will spring and cause the roller to rotate back to its normal position when the door is closed. 7

A. further object of the invention is the provision of a pulley arranged upon one 7 end of the roller.and having a rope or the like wound thereon and havingits opposite end secured to a portion of the door and which when opened will cause the rope to unwind itself upon the pulley in the process of rotating the roller and thrashing the resilient flaps arranged upon the roller which will frighten the flies or other insects from the doorway.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawings I I Figure 1 is an elevation of'a portion of a doorway and showing the manner in which the invention is applied thereto and the manner of operation thereof. 7

Figure 2 is a fragmentary longitudinal section of the roller means.

Figure 3 is a transverse section taken on line 3 3 of Figure 2.

' Referring to the drawing in detail, where in like characters of reference denote corresponding parts, the reference character 7 10 indicates a door frame and 11 the door.

It it of course obvious as shown in this invention and owing to thepurposes thereof that the door 11 is a screen door.

The invention residing in the provision of a roller 12 having a bore 13 extending an appreciable distance therein and which further includes a pulley wheel 14 upon one end thereof. Arranged in spaced relation within the bore 13 of the roller 12 is a rigid shaft 15 which hasits inner end fixed to the lower portion of the roller 12. Encircling this rigid'shaft 15 is a coiled spring 16 which has one end rigidly secured as at 17 to the inner 'end of the rigid shaft 15. A cover plate .18 is arranged or placed over end of the bore 13 and which has extending .therethrough a 6 shade roller'trunnion 19 which has its inner 20 {provided in' the outer end-of. the rigid shaft 15; this trunnion 19 includes a squared end extending within a counter-sunk portion portion 21 upon the outer end thereof. Ex-' 05' tending from the, opposite ends of the roller 12 is a companion trunnion having a rounded end portion 22, these trunnions 19 and 22 are adapted to be received within the usual and ordinary type of shade bracket 23 which in 0 this instance are secured to the inner sides of the door frame uprights as clearly illustrated in :Figure 1 of the drawing. Ar-

ranged from'end to end upon the roller 12 between the inner side of the pulley wheel 14L 7 and the opposite end of the roller 12 is a pair I of semicircular arcs 2 1 which have their adacent edges arranged. 1n spaced relation when so assembled upon the opposlte sides of the roller 12. These arcs 24 are held upon 30 the roller 12 by a pair'of companion clamps 25. Lengths of pliablepaper, oil cloth or the like as indicated at 26 are arranged upon one side of the roller 12beneath the arcs 24 whichhave their ends extending between the meeting edges of the arcs 24 and extending V therefrom an appreciabledistanceas clearly illustrated in Figure l of the drawings. Wrapped upon the pulley wheels 14 and having one end secured thereto is a length of cable or the like 27 which has its opposite end guided through a guide loop 28 secured to the inner side of the door frame 10 and thence has its end secured as at 29 to one side of the screen door 11 in order that the roller auxiliary roller30 which is arranged upon one side of the door frame ll'and which is arranged vertically therewith and which is of the usual and well known construction assemble around adoorway, I provide an 190 as in accordancewith the roller 12 and has a cable 31' extending therefrom and secured as at 82 to a suitable portion of'thedoor 11.

In the mode of operation of the present invention it is manifest that owing to the mountings and specific construction of these 1 rollers 12 and O'respectively that the same will be caused to simultaneously rotate upon the opening and closing of the door'll, that is when the door 11 is open the:cables.27 and 81 Will'be caused to unwind upon their respective pulley wheels and in so doing rotate the rollers 12 and'30 in one direction against the tension of the springs which are rigidly secured therein and upon releasing or shutting the door 11 it is noted and well, appre:

'12 and '30 and in so doing .a similar'operation is set forth when soclosing the door11'1.

The invention is susceptible of various changes'in its form, proportions-and minor details. of construction and the right is herein reserved to make such changes as properly fall within the scope of the appendedv claim.

Having thus described my invention what isclaimed is: V

In combination with a spring actuated roller, of a pairof semi-circular members carried by the roller, resilient strips extended. between the meeting edges of. the. members from the roller, and clamping bands for the roller holding 1 the members and strips against displacement. V
